Package Phase Coordination Skill

Create distributable packages including Mojo packages (.mojopkg), archives, and installation procedures.

When to Use

• Starting package phase (after Plan completes)
• Running in parallel with Test and Implementation phases
• Preparing components for distribution and reuse
• Creating installable packages or release artifacts

Quick Reference

Copy# Build Mojo package
pixi run mojo build -o packages/module.mojopkg shared/module/

# Create distribution archive
tar -czf dist/ProjectOdyssey-v0.1.0.tar.gz packages/ examples/ README.md

# Test installation
pixi run mojo run -I packages test_import.mojo

Workflow

1. Build packages - Compile Mojo modules to .mojopkg files
2. Create archives - Package distributions (tar.gz, zip)
3. Write installation docs - Document setup procedures
4. Test installation - Verify in clean environment
5. Create CI workflow - Automate packaging in GitHub Actions
6. Generate metadata - Version info, dependencies, etc.

Package Structure

Input (module source):

Copyshared/tensor/
├── __init__.mojo
├── ops.mojo
└── types.mojo

Output (packaged module):

Copypackages/
├── tensor.mojopkg
├── nn.mojopkg
└── utils.mojopkg

Distribution archive:

CopyProjectOdyssey-v0.1.0/
├── packages/
├── examples/
├── docs/
├── README.md
├── LICENSE
└── INSTALL.md

Build Configuration

Mojo package build:

Copy# Single module
mojo build -o packages/tensor.mojopkg shared/tensor/

# All modules (in loop or script)
for module in shared/*/; do
    mojo build -o packages/$(basename $module).mojopkg "$module"
done

Archive creation:

Copy# Tar.gz (Linux/Mac)
tar -czf dist/ProjectOdyssey-v0.1.0.tar.gz packages/ examples/ docs/

# Zip (cross-platform)
zip -r dist/ProjectOdyssey-v0.1.0.zip packages/ examples/ docs/

Quality Checklist

Before marking package complete:

• All modules compile without warnings
• Package can be imported in test script
• Examples run correctly
• README and INSTALL.md included
• LICENSE file present
• Version tagged correctly
• No compilation warnings
• Dependencies documented

Phase Dependencies

• Input from: Plan phase (deliverables and success criteria)
• Parallel with: Test phase (TDD) and Implementation phase
• Precedes: Cleanup phase (after parallel phases complete)

Output Location

• Packages: /packages/<module>.mojopkg
• Archives: /dist/<version>.tar.gz, .zip
• Documentation: GitHub issue comments
• Release artifacts: GitHub releases section (after cleanup)

Key Principle: Package only what's been tested and approved. No untested code in releases.
